根据条形光波导折射率数据，分别针对宽高比a:b为1:1与

2:1两种情形，设计分析 ：

1. 满足单模与双模传输的

波导尺寸范围。（需要

给出色散曲线）

2. 针对两种情形，选取你

认为最佳的波导尺寸，

计算对应的模折射率。

（计算时假设上、下包

层均很厚）-According to the refractive index of the optical waveguide stripe of data, respectively, for an aspect ratio of a: b is 1: 1 and

2: 1 both cases, the design and analysis:

1. Meet single-mode and dual-mode transmission

Bird size range. (need

Given dispersion curve)

2. For both cases, you select

That the best of the waveguide dimensions,

Computes the corresponding mode refractive index.

(Calculations assume that when the upper and lower package

Layers are very thick)
